This standard provides the measurement procedure for a fast BTI (bias temperature instability) test of metal-oxide semiconductor field-effect transistors (MOSFETs), and provides the two procedure one is the degradation at EOL (End of Life) in use condition, which are used mainly reliability design, and the other is lifetime of the targeted criteria, which are necessary for qualification of each semiconductor device application.

This document provides a methodology and test procedures to be able to declare and verify the detection area for motion detectors using Passive Infra-Red technology in switches and appliance switches whether stand-alone (direct control of one or more applications) or connected to home and building electronic systems or building automation control systems (HBES/BACS) infrastructure/networks or similar.

It also provides a uniform way to present the test results.

The purpose of these detectors is to detect the major and minor movements of persons.

Detectors may have the added aim of measuring a level of ambient natural light with respect to a reference level and triggering a number of other functions.

Safety and EMC requirements are not covered by this document.

This part of the IEC 62485 applies to the installation of one or more stationary secondary batteries having a maximum aggregate voltage of d.c. 1500 V (nominal) to any d.c. part of the power network and describes the principal measures for protections during normal operation or those that can be expected under fault conditions against hazards generated from:

–      electricity,           

–        short circuits,

–        electrolyte,

–        gas emission,

–        fire,

–        explosion.

This International Standard provides requirements on safety aspects associated with the installation, use, inspection, and maintenance of lithium-ion batteries used in stationary application.

This standard covers industrial applications in separate closed Buildings/housings as well as in public buildings, offices and private residential / homes, maintenance and disposal of lithium-ion batteries used in stationary applications. Battery energy storage system (BESS) is an application.

Batteries containing lithium metal are not covered by this standard.

Examples for the main applications are:

–        telecommunications,

–        power station operation,

–        central emergency lighting and alarm systems,

–        uninterruptible power supplies, (UPS)

–        stationary engine starting,

–        photovoltaic systems .

This part of the IEC 62485 applies to battery installation used for electric off-road vehicles and does not cover the design of such vehicles.

Examples for the main applications are:

industrial

cleaning machines

trucks for material handling e.g. lift trucks, tow trucks, automatic guided vehicles

lifting platforms electrically propulsed

other applications

electric powered boats and ships.

This International Standard covers the safety aspects of battery installation in such applications. This standard does not cover railway vehicles, for traction railway application see IEC 62928.

This standard does not cover the batteries and battery installations for the propulsion of electric road vehicles. This standard does not cover electric road vehicles according to IEC 62660 series. In the event of there being a variation of requirements between this document and a relevant product standard (e.g. goods vehicles, bicycles, wheel chairs, golf carts, etc.), then the product standard requirements take precedence.

Lithium ion cells/batteries used in traction industrial application are intended to fulfill safety requirements in accordance to IEC 62619.

The maximum voltages are limited to a.c. 1 000 V and d.c. 1 500 V  respectively and the principal measures for protection against hazards generally from electricity, gas emission and electrolyte to prevent fire and explosion are described.

This standard provides requirements on safety aspects associated with the installation, use, inspection, maintenance and disposal of batteries. Batteries containing Lithium Metal are not covered by this standard.

This document specifies the performance standards for a multiple channel transmitter/receiver chip scale package with multimode fibre interface that operates at up to 28Gbit/s per channel.  It specifies the parameters that apply, with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run as an initial design verification to prove any product’s ability to satisfy the performance standard’s requirements.

A product that has been shown to meet all the requirements of a performance standard can be declared as complying with the performance standard, but should then be controlled by a quality assurance/quality conformance program.

This document applies to the family of fibre optic filters. These components have all of the following general features:

they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port;

they modify the spectral intensity distribution in order to select some wavelengths and inhibit others;

they are fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned;

they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; the ports are optical fibre or optical fibre connectors;

they differ according to their characteristics. They can be divided into the following categories:

short-wave pass (only wavelengths lower than or equal to a specified value are passed);

long-wave pass (only wavelengths greater than or equal to a specified value are passed);

band-pass (only an optical window is allowed);

notch (only an optical window is inhibited);

gain flattening (compensating the spectral profile of the device).

It is also possible to have a combination of the above categories.

This document provides the generic information including terminology of IEC 61753-04x series documents. Published IEC 61753-04x series documents are listed in the Bibliography.

This document establishes uniform requirements for the following:

optical, mechanical and environmental properties.
